Four giant airline computer systems in the United States handle nearly all the airline reservations in the country. (They're known as CRSs, for computer reservations systems, or more often now GDS for global distribution systems.) Although each airline has a ``home'' CRS, the systems are all interlinked so that you can, with few exceptions, buy tickets for any airline from any CRS. The dominant systems in the U.S. are Sabre (home to American and US Airways), Galileo (home to United), Worldspan (home to Delta, Northwest), and Amadeus (many European lines.) The company that owned Galileo and Orbitz recently bought Worldspan, so the two GDS will presumably be merged. Many of the low-price start-up airlines don't participate in any of these systems but have their own Web sites where you can check flights and buy tickets. Southwest, the largest and oldest of the low-price airlines, doesn't participate, either. Southwest's web site gets car and hotel info from Galileo, but the info seems not to flow the other way. Orbitz one of the big three online travel agencies, runs its own system which is "direct connect" linked directly to many of the airlines.
Travel in the Middle Ages offered hardships and challenges, however, it was important to the economy and to society. The wholesale sector depended (for example) on merchants dealing with/through caravans or sea-voyagers, end-user retailing often demanded the services of many itinerant peddlers wandering from village to hamlet, gyrovagues (Wandering Monks) and wandering friars brought theology and pastoral support to neglected areas, travelling minstrels practiced the never-ending tour, and armies ranged far and wide in various crusades and in sundry other wars. Pilgrimages were common in both the European and Islamic world and involved streams of travellers both locally (Canterbury Tales-style) and internationally.
